摘　　要：本文讨论了一类斜积映射F(x,y)的周期问题,并有如下结果:若F(x,y)有m周期点,则n m,F必有n周期点.In this paper,we discussed a kind of skew product mapping cyclical issue,and has the following result：If F has a cycle of period m and if m appears before n in the sarkovskii ordering, the F has a cycle of period n.

关 键 词：自然映射 可降映射 斜积映射 周期
